Hello author, in the ex 2 (adiabatic process) the P,V,T seem to be incorrect, as the final result does not agree with the adiabatic equation PV^n = k (constant), applicable for the state P0,V0 and P2,V2. Could you please check again?

We don't need to use the specific heat ratios in this case as we are observing the same fluid, that is why here an ideal gas equation can be used to find the volume of the accumulator without any problems
